19th century printed reproduction of a still life believed to be a circa 1832 Niépce physautotype (glass original accidentally destroyed circa 1900) [1]. The physautotype (from French, physautotype) was a photographic process, invented in the course of his investigation of heliography, by Joseph Nicéphore Niépce and Louis Jacques Mandé Daguerre [2] in 1832, in which images were produced by ...
In 1829 French artist and chemist Louis Daguerre, when obtaining a camera obscura for his work on theatrical scene painting from the optician Chevalier, was put into contact with Nicéphore Niépce, who had already managed to make a record of an image from a camera obscura using the process he invented: heliography. [14] Daguerre met with ...

Still, going through cancer treatment together makes it easier at times. “Having her to just talk through things (has helped),” Katie Cooper says. Triple-negative breast cancer.
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
The research combined diverse techniques ranging from genomics, computational biology, tumour imaging, in vitro and in vivo functional models to study biological and clinical phenotypes. The proteins produced by these genes may serve as targets for novel chemotherapy drugs and other cancer treatments, or imaging scans.
Dogs with this kind of cancer that have surgery usually only survive 3 to 18 months, depending on how advanced the cancer is when found (1). Squamous cell carcinoma: This is a good possibility ...
